Proof step 6 from proof lrec (previous step)

∀ m. m +1 = n0 ∨ m +1 < n0 ↔ m < n0 ⊦ m +1 = n0 ∨ m +1 < n0 ↔ m < n0, m = n0

Heuristic cut applied rule cut formula

And obtained the following new goals

Proof step 7:
∀ m. m +1 = n0 ∨ m +1 < n0 ↔ m < n0 ⊦ m +1 = n0, m +1 = n0 ∨ m +1 < n0 ↔ m < n0, m = n0

Rule argument

fma: m +1 = n0

Additional information

Used simplifier rules: rax: ⊦ n0 < n +1 ↔ ¬ ¬(n0 = n ∨ n0 < n); Used formulas: m +1 = n0
